The Disk Plus (Failed) Wind System of 3C 47: A Story of Accretion Disks and Binary Black Holes Open
[Abridged] Optically thick, geometrically thin accretion disks around supermassive black holes are thought to contribute to broad-line emission in type-1 active galactic nuclei (AGN). However, observed emission line profiles most often dev…

Counterpart identification and classification for eRASS1 and characterisation of the AGN content Open
[abridged] Accurately accounting for the AGN phase in galaxy evolution requires a large, clean AGN sample. This is now possible with SRG/eROSITA. The public Data Release 1 (DR1, Jan 31, 2024) includes 930,203 sources from the Western Galac…

Galaxy groups in various evolutionary stages Open
Context. The formation process of galaxy groups is not yet fully understood. In particular, that of fossil groups (FGs) is still under debate. Due to the relative rarity of FGs, large samples of such objects are still missing. Aims. The pr…

Contribution of AGN to the Morphological Parameters of Their Host Galaxies up to Intermediate Redshifts of z ∼ 2 Open
The presence of Active Galaxy Nuclei (AGN) can affect the morphological classification of galaxies. This work aims to determine how the contribution of AGN affects the most-used morphological parameters down to the redshift of z ∼ 2 in COS…

Stellar populations from H-band VLT spectroscopy in a sample of seven active galaxies Open
The relationship between an active galactic nucleus (AGN) and its host galaxy is still far from being understood. Properties of the host galaxies of Seyfert nuclei, such as luminosity concentration, morphological type, metallicity, and age…
